Can thyroid cancer cause diarrhea?

Whether thyroid cancer can cause diarrhea depends on the type of thyroid cancer. If it is papillary cancer, follicular cancer or other types of thyroid cancer, it generally does not cause diarrhea. However, medullary cancer, anaplastic cancer or other types of thyroid cancer may cause diarrhea.

1. Papillary carcinoma: Papillary carcinoma is a common type of thyroid cancer. It is a low-grade malignant tumor. Patients usually have no obvious symptoms, and some patients may have lumps in the neck. Papillary carcinoma generally does not cause diarrhea.

2. Follicular carcinoma: Follicular carcinoma is also a common type of thyroid cancer. It is a moderately malignant tumor. Patients may experience symptoms such as hoarseness and difficulty swallowing. Since follicular carcinoma has little impact on the body, it will not cause diarrhea.

3. Medullary carcinoma: Medullary carcinoma is a rare thyroid malignancy and a highly malignant tumor. Patients may experience diarrhea because medullary carcinoma affects the digestive system, causing diarrhea.

4. Undifferentiated cancer: Undifferentiated cancer is a type of thyroid malignant tumor and is a highly malignant tumor. Patients may experience symptoms such as nausea, vomiting, and loss of appetite. Undifferentiated cancer can affect the gastrointestinal tract, causing diarrhea.

If you suspect you have thyroid cancer, it is recommended that you go to the hospital in time, complete relevant examinations under the guidance of a doctor, and actively cooperate with the doctor's treatment. In daily life, you should pay attention to rest, maintain adequate sleep time, and avoid staying up late.
